UK – Another Crusie Ship Virus Outbreak

BBC News

A cruise ship delayed its departure from Southampton after a suspected outbreak of norovirus on board. Celebrity Cruises’ vessel Constellation arrived in the city’s port at 06:00 GMT at the end of a 12-night cruise. Southampton’s Port Health Authority said about 350 passengers had fallen ill with the vomiting and diarrhoea bug. Its departure was delayed until 20:00 while deep cleaning took place.

The authority’s Rosie Zambra confirmed it was informed of “concerns over an increased levels of what appeared to be norovirus” several days before the ship’s arrival.

USA – Norovirus Outbreak at a Restaurant

Food Safety News 

At least 39 people fell ill with Norovirus infections after eating at a restaurant in central Illinois last week, according to the local health department.

All of those sickened were among a group of 80 people who attended an end-of-year banquet for a high school soccer team at Alexander’s Steakhouse in Peoria, IL October 28, reported the Peoria Journal Star.

Though the restaurant served a total of 1,100 meals the weekend the banquet was held, no patrons other than those who attended the banquet contracted the virus.

Victims experienced typical symptoms of Norovirus infection, including vomiting, diarrhea and abdominal cramps.

CDC Letter – UK Shellfish Market and Viruses – Hepatitis E

CDC (full letter)

Bivalve mollusks (shellfish), such as mussels and oysters, are filter feeders; they concentrate microorganisms of human and animal origin (up to 100×) from the surrounding environment. Several recent reports have linked the incidence of human infection with hepatitis E virus (HEV) to consumption of undercooked pork, game products, and shellfish (1,2). Infectious HEV has been found in swine manure and wastewater (3); therefore, application of manure to land and subsequent runoff could contaminate coastal water, leading to contamination of shellfish and, subsequently, possible human infection. Because they are filter feeders, bivalve mollusks are biologically relevant sentinels and can indicate potential pathogens that are contaminating the environment. It is essential to ensure that this sustainable resource of coastal areas, where mussels and oysters are farmed or collected wild, is not subjected to environmental contamination that could lead to public health risks.

Risk management for bivalve mollusks, aimed at control of fecal pollution, relies heavily on the use of Escherichia coli as an indicator of fecal (sewage) contamination and is enacted under European food regulations (Regulation 854/2004, www.cefas.co.uk/media/455777/extract_reg_no_854_2004.pdf Adobe PDF file). However, although these regulations probably reduce the number of infections, especially bacterial infections, they are not viewed as adequately controlling the risk for viral infections. Specific risks are posed by the robustness of viruses in the environment and the different behavior of viruses within bivalve mollusks compared with behavior within bacterial fecal indicators.

Canada – Montreal – Norovirus Hospital Outbreak

CBC News

An outbreak of norovirus among staff members at Montreal’s Jewish General Hospital led to the temporary closure of the hospital’s neurology clinic last week, CBC has learned.

About 45 employees at the hospital came down with gastrointestinal symptoms, including diarrhea, cramps and fever, after eating food that may have originated in an in-house catering service that is only used by staff.

The service is run by the hospital’s Atrium Café, a franchise operated by a volunteer auxiliary, which also serves hundreds of staff and visitors to the hospital each day.

The coffee shop is independent of the hospital’s main cafeteria.

“We closed the coffee shop immediately on Thursday afternoon,” said hospital spokesman Glenn Nashen. “Tests were done all day Friday, and although nothing has been conclusive at this point, the suspicion is that [the virus] may have come from this catering service.”

Nashen said as far as the hospital knows, only staff at the hospital caught the virus.

So many staff members in the neurology department fell ill that the neurology clinic had to be closed for half a day on Thursday and all of Friday.

The neurology clinic is expected to be open again on Monday.

Until the infection prevention and control team determines the specific cause of the outbreak, the coffee shop will remain closed, Nashen said

German Norovirus Outbreak – Chinese Strawberry’s Implicated

Business Insider

It started on September 19. In the East German states of Brandenburg, Saxony, Berlin, Thuringia, and Saxony-Anhalt, a lot of children and adolescents as well as a few adults suddenly fell ill with vomiting and diarrhea.

Turns out, a wholesaler had sold contaminated frozen strawberries to commercial kitchens of three companies that made cafeteria food for schools and kindergartens, among them Sodexo. Sources among the food investigators stated that the strawberries had most likely come from China.

When the strawberries were thawed to be used in desserts, they weren’t always fully heated, and the noroviruses, which are particularly resistant to cold and heat, survived. The different thawing processes used in various facilities could explain why infections occurred in some schools but not in others, though all used the strawberries from the same shipment.

German Foodborne Virus Outbreak 6,500 Cases

Reuters

More than 6,500 German children and teenagers have fallen ill with diarrhea and vomiting that health authorities say has likely been caused by a food-borne virus in meals delivered to schools and day care centers.

Regional health ministries and a top health research institute said youngsters from five of Germany’s 16 states had been affected by the acute gastroenteritis, with the first cases registered on Tuesday. So far, those affected had not suffered any complications.

“All the institutions which have registered cases of the illness so far are probably being provided by the same caterer,” wrote the Robert Koch Institute, which researches and advises the German health ministry on infectious diseases. “This suggests that it is an outbreak caused by food.”

The German government and affected states have established a task force charged with looking for the reason for the illness in order to prevent it spreading any further.

Norovirus – Wales and New Zealand

BBC News

A total of 74 people have become ill after visiting a hotel in Newport.

An investigation is being carried out after 51 guests and 23 staff were affected by a viral infection, which is probably norovirus, at the Hilton Hotel in Langstone.

They started to become ill last Tuesday and suffered diarrhoea and vomiting.

Hilton Worldwide said the wellbeing of guests and staff was of “paramount importance” and it had brought in “stringent” health and safety measures.

Public health officials say the outbreak is not linked to a particular function or event, but the virus was passed by someone originally infected.

Newport council alerted Public Health Wales two days after the first illnesses.

Virus outbreak hits Wellington childcares, resthomes

Outbreaks of norovirus and rotavirus have been reported at Wellington childcare centres and resthomes.

Regional Public Health had responded to outbreaks of gastroenteritis at four childcare centres and two rest homes since the beginning of the month, medical officer of health Jill McKenzie said.

The number of outbreaks was higher than usual and indicated stomach bugs were circulating in the community.

“The nature of these bugs is they don’t tend to infect one person because their viruses are quite infectious.

Commonwealth Games Venue – Norovirus?

ScotsmanNorovirus

A SPORTS event due to be held at a major Commonwealth Games venue has been cancelled due to fears participants might contract the norovirus bug.

 The Great Scottish Swim at Strathclyde Country Park in Motherwell was set to take place this weekend, but it has been called off over fears the rising water level would push the bug numbers above the safe mark.

The swimming element of a triathlon planned to be held in Strathclyde Loch on Saturday has been removed due to safety concerns over the sickness bug.

In June, the same loch was closed for water sports use for two months after a swimmer contracted the norovirus.

The levels of the potentially harmful toxic blue-green algae in the loch were found to be twice the recommended “safe” limit by the Scottish Environmental Protection Agency ahead of the event.
